Add ‘Show Desktop’ to Dock Panel in Ubuntu 20.04 & 18.04

Last updated: September 24, 2023

This simply tutorial shows how to add a ‘Show Desktop‘ icon into the left dock panel in Ubuntu 21.10, Ubuntu 20.04, or Ubuntu 18.04 with default GNOME desktop.

The ‘Show Desktop‘ button was dropped since Ubuntu switched to Gnome 3 Desktop. For those using desktop app shortcuts, it’s useful to have a button to toggle display blank desktop quickly. And to add it back, you can manually create shortcut icon to do the trick and add it to panel (dock).

As you may know, the keyboard shortcuts Ctrl+Alt+d or Super+d do the function hide or show all opened app windows. And following steps will create a ‘show desktop’ shortcut icon simulates the keyboard press (Super+d) via the xdotool tool.

NOTE that following steps don’t work on Wayland session, since xdotool simulates X11 keyboard/mouse input events.

1. Install xdotool:

Xdotool is a command-line X11 automation tool, that allows to simulate keyboard input and mouse activity, move and resize windows, etc.

To install it, open terminal either by pressing Ctrl+Alt+T key combination on keyboard, or by searching from the activities overview screen. When terminal opens, paste the command below into it and hit run:

sudo apt-get install xdotool

Type your user password (no asterisk feedback) when it prompts and answer y to confirm.

2. Create a shortcut icon for Show Desktop:

Most Linux distributions identify app shortcut icons via .desktop file under “/usr/share/applications” for global or ‘.local/share/applications’ for local user only.

To create an app shortcut in the case, run command in terminal:

gedit ~/.local/share/applications/show-desktop.desktop

This command will create and also open it via gedit text editor. When the file opens, copy and paste the lines below and save it.

[Desktop Entry]
Type=Application
Name=Show Desktop
Icon=desktop
Exec=xdotool key --clearmodifiers Super+d

3. Add show desktop to dock panel:

After created the shortcut, either press Windows (or Super) key on keyboard or click upper-left corner ‘Activities’ to bring up the overview screen.

Then search for ‘Show Desktop’ (without quotes), right-click on the result icon and select ‘Add to Favorites’.

Finally, you’ll see the ‘Show Desktop’ icon on the dock panel. As mentioned, it works only on Xorg session. For Ubuntu 21.04 and higher, you may need to choose ‘Ubuntu on Xorg‘ from the login screen via the gear button.

That’s all. Enjoy!

    Linux Kernel 4.19 Released, How to Install it in Ubuntu

    Last updated: October 23, 2018

    Linux Kernel

    Linux Kernel 4.19 LTS (Long Term Support) was released yesterday. Instead of Linus, Greg KH announced the new 4.19 release and wrote lots of words:

    While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone.

    A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so the next -rc1 merge window is going to be bigger than “normal”, if there is such a thing as “normal” for our rate of development.

    And speaking of development, there’s that other thing that happened this release cycle, that ended up making it such that I’m the one writing this instead of Linus. Allow me the guilty pleasure of taking a few minutes to talk about that….

    …

    What’s New in Kernel 4.19 (via omgubuntu.co.uk):

    • An alternate mode driver for USB Type-C/DisplayPort Type-C support
    • Better support for Intel’s Low Power Subsystem (LPSS)
    • Support for Qualcomm Adreno 600 series hardware
    • Initial support for Intel Icelake graphics
    • Armada atomic mode-setting
    • Ongoing DRM improvements
    • x86 KVM improvements
    • In-kernel GPS subsystem
    • General touchscreen improvements
    • Initial support for the 802.11ax WLAN
    • Various Filesystem improvements
    • Obligatory Linux power management tweaks
    • Continued Y2038 prep

    How to Install Linux Kernel 4.19 in Ubuntu:

    There are a few third-party tools, e.g., UKTools and Ukuu, make it easy to install the latest Kernel in Ubuntu.

    You can also manually download the Kernel 4.19 Ubuntu binary packages at:

    Download Kernel 4.19

    Depends on your OS type, download and install the packages in turns:

    1. linux-headers-4.19.0-xxxxxx_all.deb
    2. linux-headers-4.19.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
    3. linux-modules-4.19.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
    4. linux-image-xxx-4.19.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

    Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

    Also you can download and install the kernel binaries via terminal commands:

    For 64-bit OS:

    cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-image-unsigned-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb

sudo dpkg -i *.deb

    for 32-bit OS:

    cd /tmp/

wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb

sudo dpkg -i *.deb

    Once installed, restart your computer and enjoy!

    Restart your machine and select boot with the previous kernel in boot menu ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 4.19.0:

    sudo apt remove --autoremove avidemux2.6-qt avidemux2.6-plugins-qt

    2. Add the PPA repository by running command in terminal:

    sudo add-apt-repository ppa:ubuntuhandbook1/avidemux

    Type user password (no asterisks feedback) when it prompts and hit Enter to continue.

    3. Finally install Avidemux 2.7.1 via command:
